Answer: #20, x = 3

#21, x = 1/2

Step-by-step explanation:

#20) x + 4 + x + 2+ x + 5 = x + 3 +x+3+x+1+x+1

3x + 11 = 4x + 8

-3x -3x

11= x + 8

- 8 - 8

3 = x

#21) 12x(5) = 6x + 9 + x + 10 + x + 7

60x =8x + 26

-8x -8x

52x = 26

divide both sides by 52

x = 1/2

In the school library, 28% of the books are non-fiction. If there are 1.224 fiction books in

denis-greek [22]

Answer:

1700 books

Step-by-step explanation:

We are given;

% of non-fiction books in the library as 28%
Number of fiction books in the library as 1,224 books

We are required to determine the total number of books.

First we determine the percentage of non-fiction books

We need to know that;

% of fiction books + % of non-fiction books = 100%

Therefore;

% of non-fiction books = 100 % - 28 %

= 72%

Second we determine the total number of books

We know that;

Total number of books = 100%

But;

72% = 1,224 books

Therefore;

Total number of books = (1,224 × 100%) ÷ 72%

= 1700 books

Hence, the library has a total number of 1700 books

Which pairs of angles in the figure below are vertical angles?

ch4aika [34]

Answer: Option A and Option C.

Step-by-step explanation:

For this exercise it is important to know the definition of "Vertical Angles".

When two lines intersect or cross, there are a pair of angles that share the same vertex and they are opposite each other. This pair of angles are known as "Vertical angles".

By definition, Vertical angles are congruent, which means that the have the equal measure.

In this case, you can observe in the picture provided in the exercise that the line TI and the line WN intersect each other at the point S.

You can identify that the pair of angles that are opposite to each other and share the same vertex are the shown below:

$\angle ISN$ and $\angle TSW$

$\angle TSN$ and $\angle ISW$

I need answers!!!!!!!!

Answer:

a) 4.4583 b) Fiona

Step-by-step explanation:

First find the average of the numbers by adding them all together then dividing them by the amount of numbers given:

$(85 + 88 + 90 + 91 + 93 + 96 + 97 + 97 + 98 + 98 + 99 + 105)\div12= 1137\div12= 94.75$

Then find the difference between each number and the answer you got

$(85 - 94.75) + (88 - 94.75) + (90 - 94.75) + (91 - 94.75) + (93 - 94.75) + (96 - 94.75) + (97 - 94.75) + (97 - 94.75) + (98 - 94.75) + (98 - 94.75) + (99 - 94.75) + (105 - 94.75)\div12$

Which is

$(9.75) + (6.75) + (4.75) + (3.75) + (1.75) + (1.25) + (2.25) + (2.25) + (3.25) + (3.25) + (4.25) + (10.25)\div12$

Which comes out to

$\frac{53.5}{12}=4.4583$
